I have some question in the relation matching

[ShaoZhangHao]

@apoorvumang Hi, your code and paper are helpful for my study.
I have a question that you said using the relation‘s embedding dot product with question's embedding to get scores S(r,q) in the section relation matching.
But I don't find how did you get the relation's embedding and dot product with question's embedding.
And I also don't know that what is the funtion of "applynonlinear()" ?
Could you help me to solve these problems? Thanks
